Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, specifically to a snow removal device for the top of an air-supported membrane structure. Background Technology

[0002] Air-supported membrane structures are curved, and large-span air-supported membrane structures have a large top surface and a gentle slope. In snowy northern regions, large-span air-supported membrane structures are prone to snow accumulation on their tops. As the snow accumulation area and thickness increase, when the snow load exceeds the design load of the air-supported membrane structure, it can cause adverse conditions such as sagging, affecting the safe use of the air-supported membrane structure. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of easy snow accumulation on the top of the air film in northern regions and areas with high snow load in the prior art, thereby providing a snow removal device for the top of the air film.

[0005] A snowplow has wheels on both sides in the axial direction, and multiple snowplows are spaced apart on the top of the air-supported membrane structure and extend along the axial direction of the top air-supported membrane structure.

[0006] The traction mechanism, which is set on both sides of the air-supported membrane structure, is used to traction the snowplow to reciprocate along the radial direction of the top of the air-supported membrane structure. It includes a traction cable and a traction machine. The traction machine is set on the retaining wall of the air-supported membrane structure in the direction of the reciprocating movement of the snowplow. One end of the traction cable is connected to the traction machine, and the other end is connected to the snowplow through a traction point.

[0012] The technical solution of this utility model has the following advantages:

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] A snow removal device for the top of an air-supported membrane structure, such as Figures 1-3 As shown, it includes a snowplow 1 and a traction mechanism 2 for driving the snowplow 1 to reciprocate.

[0027] The snowplow 1 has six evenly spaced wheels on both sides in the axial direction. The number of wheels can be adjusted according to the actual situation on site. Multiple snowplows 1 are evenly spaced on the top of the air membrane structure and extend along the axial direction of the top air membrane structure.

[0028] The traction mechanism 2 is located on both sides of the air-supported membrane structure and is used to traction the snowplow 1 to reciprocate along the radial direction of the top of the air-supported membrane structure. It includes a traction cable 21 and a traction machine 22. Four traction machines 22 are set on the retaining wall under the eaves of the air-supported membrane structure in the direction of the reciprocating movement path of the snowplow 1. Two traction machines 22 are set on each side retaining wall. The distance between two adjacent traction machines 22 is determined according to the working distance of the traction cable 21 as it descends along the traction cable guide pulley 4. One end of the traction cable 21 is connected to the traction machine 22, and the other end is connected to the snowplow 1 through the traction point 3.

[0029] In this embodiment, the snowplow 1 includes a frame and a body formed by stainless steel plates anchored to the frame. The frame is made and reinforced with aluminum alloy square tubing to ensure that the body does not deform during operation. After the snowplow 1 is installed, a gap should be maintained between it and the membrane surface of the air-supported structure.

[0030] In this embodiment, the wheel axle is made of stainless steel. To prevent damage to the membrane surface from the wheel, the wheel gears are made of rubber, and the wheel hub is made of metal, resin, or rubber. To prevent wheel slippage, the ends of the gears are trapezoidal. The outer diameter of the wheel, as well as the length, thickness, and net distance between the outer edges of the gears, should be sufficient to allow passage over the net and the guardrail.

[0031] In this embodiment, two traction points 3 are provided on the lower frame of both sides of the snowplow 1 in the axial direction. The two traction points 3 on each side are respectively set at 500mm from both ends of the vehicle body. The traction points 3 on both sides are symmetrically arranged to ensure balance during operation. The setting points of the traction points 3 on the vehicle body can be adjusted according to the pulley track of the traction cable 21 to avoid excessive contact of the traction cable 21 with the membrane or cable and to prevent tipping during traction work. The vehicle body at the location of the traction points 3 should be reinforced.

[0032] In this embodiment, a towing hook is provided at towing point 3, which is connected to the vehicle frame by a non-rigid or galvanized pull ring bolt, and has a double nut structure.

[0033] In this embodiment, to prevent precipitation from affecting the normal operation of the traction machine 22, a protective cover is installed on the traction machine 22. The operation of the traction machine 22 should be synchronized (select equipment of the same model, install a wireless remote control to achieve synchronization, or add other synchronization control devices) to ensure that the snowplow 1 operates stably on top of the membrane.

[0034] In this embodiment, a traction cable guide pulley 4 is installed at the net cable position below the slope of the air-supported membrane structure along the movement path of the snowplow 1. For example... Figure 4 As shown, when the guide pulley 4 of the traction cable is installed at the intersection of the net cable, a cross-shaped bayonet is used as a connecting base, and the guide pulley is welded onto the cross-shaped bayonet; as Figure 5 As shown, when the traction cable guide pulley 4 is installed on a single cable, a balance plate needs to be added to the cross-shaped clamp to prevent the guide pulley from tilting. The number and installation position of the traction cable guide pulley 4 can be adjusted according to the actual site conditions.

[0035] In this embodiment, when using the snow removal device, the traction motors 22 on both sides of the snowplow 1 are activated, causing one traction motor 22 to retract and the other traction motor 22 to release, allowing the traction cable 21 to move the snowplow 1 to one side. Once the snowplow 1 has moved to the slope position of the air-supported membrane structure, the traction motor 22 is stopped, the other traction motor 22 is retracted, and the one traction motor 22 is released. After the snowplow 1 has moved to the slope position on the other side of the air-supported membrane structure, it is reset. During the movement of the snowplow 1, care should be taken to avoid it moving too far and colliding with the guide pulley 4 of the traction cable.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
